Hipovitaminose A em Testudines

Os Testudines possuem uma dieta bastante variada e, em cativeiro, esses animais são comumente afetados por um desbalanceamento nutricional, fazendo com que surjam diversas enfermidades. Um dos distúrbios mais frequentes encontrados é a hipovitaminose A, já que alguns répteis não absorvem de forma adequada o betacaroteno, sendo necessário a reposição na
